today i was rideing my ATV with a girl, and i had an erection and i had to uraniate. i hink i may have goten some sperm on my underware. i did not like make a cum-shot but i think some came up my urethra. this happened while she was driveing and i was on the back. i am sure when we hit bumps she landed on my penis. she was wareing jean shorts, and underware. and i was wareing shorts and underware, i saw only a few rely small wet spots on my underware and i don't think there are any on the outside of my shorts, do you think she could get pregnant?
